This is a fun way to work on identifying letters. Put letters (magnetic letters, foam letters, or letters on paper) into a bucket. Have your child draw a letter out of the bucket, find it on the page, and stamp it (or put a sticker on it, or color it in, etc.) Continue until an entire row or page is filled.
If you'd like to try it with lowercase letters, use this page. You may want to download and then edit the font. I originally used this lowercase page for a font sort so the g and the a might not be what you are looking for.
